Description

Technical Field

[0001] The present invention relates to the technical field of biological sample storage, and in particular to an automatic conveying device for low-temperature storage of biological samples. Background Art

[0002] Biological samples refer to samples of biological macromolecules, cells, tissues and organs from healthy or diseased organisms, such as blood samples, tissue sections, urine samples, fecal samples, etc. Currently, biological samples are usually collected in test tubes and stored, and then the test tube racks containing the test tubes are stored at low temperatures. When biological samples are stored and transported at low temperatures, automatic guided vehicles are usually used to automatically transport the low-temperature stored biological samples. The movement of the automatic guided vehicle can be remotely controlled to avoid the safety hazards caused by human operation.

[0003] When storing test tube racks containing biological samples, the test tube racks are usually centrally mounted inside a low-temperature storage container. When taking one or several test tubes containing biological samples, the low-temperature storage container needs to be fully opened for operation. The large opening may cause rapid loss of cold source, resulting in a decrease in the thermal insulation performance of the low-temperature storage container. If the biological samples are exposed to a non-low-temperature environment for a long time, there will be a certain risk of destructive damage to the biological samples, which will greatly reduce the storage effect of the biological samples.

[0012] As a further solution of the present invention, the locking assembly includes two clamping strips, which are hook-shaped and clamped in the positioning groove. The clamping strips are slidably connected in the slide, and two sliding rods are fixedly connected to the inner wall of the slide. The clamping strip passes through and is slidably connected to the outside of the two sliding rods. A second spring is connected to the outer shell of the sliding rod, one end of the second spring is fixed to the inner wall of the slide, and the other end of the second spring is fixedly connected to one side of the clamping strip, and a handle is fixedly connected to the side of the clamping strip away from the positioning groove.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The present invention places test tubes containing biological samples in tube grooves on the tube rack, limits the test tubes by the tube grooves, and improves the safety of storage and transportation. After completing the placement of the test tubes, the cover is pushed to make the cover drive the tube rack and the column to slide in the storage groove. When the cover is close to the low-temperature storage box, the two clamping strips will contact the positioning grooves outside the low-temperature storage box. When the clamping strips slide into the positioning grooves, the elastic force of the second spring can squeeze the two clamping strips so that the two clamping strips move away from each other and embed into the positioning grooves, thereby achieving the purpose of locking the cover and the tube rack. Similarly, the tube racks at other positions on the low-temperature storage box can be operated to perform zoned low-temperature storage of test tubes of different categories containing biological samples, so as to facilitate subsequent targeted taking and placing work. When taking out one or several test tubes, by squeezing The two handles drive the two clamping strips to approach each other, and the clamping strips release the locking state with the positioning groove. Secondly, the cover plate can be pulled outward by the handles to take out the tube rack from the storage tank. If a single test tube is taken out, only a single tube groove on the tube rack is exposed to the outside during the movement of the tube rack, and the other tube grooves and test tubes on the tube rack are still located inside the low-temperature storage box. Because the part between the two tube grooves on the tube rack can fit with the two sides of the inner wall of the storage tank, the cold source inside the low-temperature storage box will not be lost, thereby ensuring the thermal insulation performance of the low-temperature storage box. Moreover, test tubes of the same type containing biological samples are placed on multiple independent tube racks respectively. One of the tube racks can be drawn out for taking and placing, without the need to fully open the low-temperature storage box, to prevent the biological samples from being exposed to a non-low-temperature environment for a long time and causing damage to themselves, thereby improving the storage effect of the biological samples.

[0014] 2. When the present invention uses an automatic guided vehicle to transport test tubes containing biological samples in a low-temperature storage box, the automatic guided vehicle is remotely controlled to move to the bottom of the support plate, so that the embedded seat on the top plate is located directly below the embedded groove, and the two electric hydraulic rods are controlled to extend and drive the top plate to move up, so that the top plate drives four or more limiting columns and the embedded seat to move up, and the limiting columns with a conical design can slide into the limiting groove, so as to calibrate the center of the support plate and the top plate, so that the embedded seat can be stably inserted into the embedded groove. Because the top of the card block on the embedded seat is designed with an inclined surface, the two card blocks will approach each other when squeezed by the embedded groove. After the embedded seat completely slides into the embedded groove, the elastic force of the first spring drives the slider to insert the card block into the installation groove, so as to achieve the purpose of locking the embedded seat and the top plate. After the assembly work between the automatic guided vehicle and the low-temperature storage box is completed, the automatic guided vehicle can drive the support plate, the mounting seat and the low-temperature storage box to move when the automatic guided vehicle is working, thereby realizing the purpose of automatically transporting the biological samples. When separating the automatic guided vehicle and the low-temperature storage box, the electromagnetic seat is controlled to work so that the magnetic suction plates on both sides of the electromagnetic seat can attract the metal adsorption sheet on the slider, so that the slider drives the card block to leave the mounting groove. Secondly, the electric hydraulic rod is controlled to contract and drive the top plate to move downward, so that the top plate drives the embedded seat to leave the embedded groove, and the automatic guided vehicle moves out from under the support plate, and the assembly of the automatic guided vehicle and the low-temperature storage box can be released, so that the automatic guided vehicle can automatically transport the low-temperature storage boxes in batches, and the overall operation does not require human assistance, further improving the transportation efficiency of biological samples.

[0020] As a further solution of the present invention, the support assembly 4 includes a support plate 401, a mounting seat 402 is provided on the support plate 401, support legs 403 are fixedly connected at the four corners of the bottom of the support plate 401, and a universal wheel 404 is installed at the bottom of the support leg 403. Four limiting grooves 405 are provided between the four support legs 403. The limiting grooves 405 are opened at the bottom of the support plate 401, and an embedding groove 406 is opened at the center position of the bottom of the support plate 401.

The top of the jacking assembly 5 is set in the limiting groove 405, the embedding seat 6 is clamped in the embedding groove 406, and the two sides of the mounting assembly 7 are clamped in the two mounting grooves 407.

[0021] During operation, the embedding seat 6 can be inserted into the embedding groove 406 during the upward movement, and can connect the support plate 401 with the top plate 501, thereby limiting the support plate 401 and the low-temperature storage box 8 above, making it convenient for the top plate 501 to drive the support plate 401 and the low-temperature storage box 8 to move.

The electric hydraulic rod 502 can be extended and retracted to facilitate the adjustment of the height of the top plate 501 and the embedded seat 6, so as to facilitate the insertion or removal of the embedded seat 6 into the embedded groove 406.

[0024] As a further solution of the present invention, the installation component 7 includes an electromagnetic seat 701, which is installed in the middle of the embedded seat 6. Magnetic plates 702 are respectively provided on both sides of the electromagnetic seat 701. Sliders 703 are respectively provided on the sides of the two magnetic plates 702 away from each other. The slides 703 are slidably connected in the embedded seat 6. A metal adsorption sheet 705 is installed on the side of the slide 703 close to the magnetic plate 702. A clamping block 704 is fixedly connected to the side of the slide 703 away from the electromagnetic seat 701. The clamping block 704 is clamped in the installation groove 407. The top of the clamping block 704 is inclined and its shape is adapted to the installation groove 407. The embedded seat 6 is clamped in the embedded groove 406.

[0026] As a further solution of the present invention, the freezing assembly 9 includes a refrigeration mechanism 901, which is installed in the middle of the low-temperature storage box 8. A temperature controller 902 is installed on the top of the refrigeration mechanism 901. A plurality of refrigeration rods 903 are provided outside the refrigeration mechanism 901. The refrigeration rods 903 pass through the top of the low-temperature storage box 8 and are located between two adjacent storage tanks 10.

[0027] During operation, since the refrigeration mechanism 901 is located in the middle of the low-temperature storage box 8, the cold source can be evenly introduced into multiple storage slots 10, and the setting of the temperature controller 902 can automatically adjust the temperature in the low-temperature storage box 8. Since the refrigeration rod 903 is located between two adjacent storage slots 10, the cold source can be evenly introduced into the test tubes in the storage slots 10, further improving the low-temperature storage effect.

[0028] As a further solution of the present invention, the mounting assembly 12 includes a pipe rack 121, which is arranged in the storage tank 10. The side of the pipe rack 121 away from the cover plate 13 is fixedly connected to a column 122, and the column 122 is slidably connected in the storage tank 10. The column 122 is designed as an arc surface near the interior of the storage tank 10. A plurality of pipe grooves 123 are opened on the pipe rack 121, and openings 124 are respectively opened on both sides of the inner wall of the pipe groove 123, and a leakage hole 125 is opened at the bottom of the pipe groove 123.

[0029] During operation, the test tube is placed in the tube groove 123 on the tube rack 121. The test tube is limited by the tube groove 123 to improve the safety of storage and transportation. The setting of the opening 124 enables the cold source in the cooling rod 903 to contact the outer wall of the test tube to improve the cooling effect. The setting of the leakage hole 125 enables the residual liquid to be discharged from the tube groove 123 to prevent the residual liquid from freezing the test tube in the tube groove 123 and making it difficult to remove.

[0030] As a further solution of the present invention, the locking assembly 15 includes two clamping strips 151, which are hook-shaped and clamped in the positioning groove 16. The clamping strips 151 are slidably connected in the slide 14, and two sliding rods 152 are fixedly connected to the inner wall of the slide 14. The clamping strip 151 passes through and is slidably connected to the outside of the two sliding rods 152. A second spring 153 is connected to the outer shell of the sliding rod 152, one end of the second spring 153 is fixed to the inner wall of the slide 14, and the other end of the second spring 153 is fixedly connected to one side of the clamping strip 151, and a handle 154 is fixedly connected to the side of the clamping strip 151 away from the positioning groove 16.

[0031] During operation, the elastic force of the second spring 153 can squeeze the two clamping strips 151 so that the two clamping strips 151 move away from each other and embed into the positioning groove 16, thereby achieving the purpose of locking the cover plate 13 and the tube rack 121, preventing the cover plate 13 from driving the tube rack 121 to slide out of the storage tank 10 during the movement of the low-temperature storage box 8, thereby improving the stability of the automated transportation of the test tubes containing biological samples.

[0032] The working principle of the present invention is as follows: when in use, a test tube containing a biological sample is placed in the tube groove 123 on the tube rack 121. After the test tube is placed, the cover plate 13 is pushed, so that the cover plate 13 drives the tube rack 121 and the column 122 to slide in the storage groove 10. When the cover plate 13 is close to the low-temperature storage box 8, the two clamping strips 151 will contact the positioning groove 16. When the clamping strip 151 slides into the positioning groove 16, the elastic force of the second spring 153 can squeeze the two clamping strips 151, so that the two clamping strips 151 are embedded in the positioning groove 16, thereby achieving the purpose of locking the cover plate 13 and the tube rack 121. Similarly, the tube racks 121 at other positions on the low-temperature storage box 8 can be locked to different types of tube racks containing biological samples. The test tubes are stored in a partitioned low-temperature storage. When taking out one or more test tubes, the two handles 154 are squeezed to make the two handles 154 drive the two clamping strips 151 to move closer to each other. Then, the cover plate 13 is pulled outward by the handles 154 to bring the tube rack 121 out of the storage tank 10. If a single test tube is taken out, only a single tube groove 123 on the tube rack 121 is exposed to the outside during the process of moving the tube rack 121, and then the tube is taken out. The other tube grooves 123 on the tube rack 121 and the test tubes are still located inside the low-temperature storage box 8. Because the part between the two tube grooves 123 on the tube rack 121 can fit on both sides of the inner wall of the storage tank 10, the cold source inside the low-temperature storage box 8 will not be lost, and the low-temperature storage box 8 will be transported. When the automatic guided vehicle 1 is remotely controlled to move to the bottom of the support plate 401, the embedded seat 6 on the top plate 501 is located directly below the embedded groove 406, and the two electric hydraulic rods 502 are controlled to extend and drive the top plate 501 to move upward, so that the top plate 501 drives the four or more limiting columns 503 and the embedded seat 6 to move upward. After the embedded seat 6 completely slides into the embedded groove 406, the elastic force of the first spring 706 drives the slider 703 to drive the card block 704 to be stuck in the installation groove 407, so as to achieve the purpose of locking the embedded seat 6 and the top plate 501, and the assembly work between the automatic guided vehicle 1 and the low-temperature storage box 8 is completed. When the automatic guided vehicle 1 is working, it can drive the support plate 401, the mounting seat 402 and the low-temperature storage box 8 to move upward. And the low-temperature storage box 8 is moved, and the universal wheel 404 at the bottom of the supporting leg 403 can roll on the ground. When separating the automatic guided vehicle 1 and the low-temperature storage box 8, the electromagnetic seat 701 is controlled to work, so that the magnetic suction plates 702 on both sides of the electromagnetic seat 701 can attract the metal suction plate 705 on the slider 703, so that the slider 703 drives the block 704 to disengage from the installation groove 407, and then the electric hydraulic rod 502 is controlled to shrink and drive the top plate 501 to move downward, so that the top plate 501 drives the embedded seat 6 to disengage from the embedded groove 406, and the automatic guided vehicle 1 moves out from under the supporting plate 401, so that the automatic guided vehicle 1 can release the assembly of the low-temperature storage box 8, so that the automatic guided vehicle 1 can automatically transport other low-temperature storage boxes 8.
